The <info>doctrine:fixtures:load</info> command loads data fixtures from your bundles:

  <info>./app/console doctrine:fixtures:load</info>

You can also optionally specify the path to fixtures with the <info>--fixtures</info> option:

  <info>./app/console doctrine:fixtures:load --fixtures=/path/to/fixtures1 --fixtures=/path/to/fixtures2</info>

If you want to append the fixtures instead of flushing the database first you can use the <info>--append</info> option:

  <info>./app/console doctrine:fixtures:load --append</info>

By default Doctrine Data Fixtures uses DELETE statements to drop the existing rows from
the database. If you want to use a TRUNCATE statement instead you can use the <info>--purge-with-truncate</info> flag:

  <info>./app/console doctrine:fixtures:load --purge-with-truncate</info>
